[Interest] Qt 5.5 for ios: frameworks support seems to be broken

[Nuno Santos]

In my case the problem was that I was linking to a framework called parse and inside the project dir there was a parse dir. For some reason that directory with the name of the framework I was linking was making the linker line to become "-framework “ invalidating all the frameworks in the line from that point onward. This didn’t happened on 5.4.1. I think something changed on qmake. I can’t tell you exactly what it was.

Try to link frameworks one by one and see which was is failing. You can also share your linker command execution line. Maybe I can spot something. 

Regards,

Nuno
